LightLEEDer Serial Interface Control Modules

Model: LLSI

The LightLEEDer Serial Interface Module can be added to any panel to provide control from any building automation system using BACnet IP, BACnet MSTP, Modbus RTU, Modbus  ASCII, Modbus TCP or Metasys N2. With the panel module, commands can be sent to the panel to force relays ON and OFF, force relays On and OFF with a timer option (blink, double Blink, HID delay, Alarm ON, Alarm OFF, Pulse ON, and Pulse OFF), monitor relay status, monitor input status, and enable/disable inputs. A single point gateway is available for control and Status of relays, groups, and presets on the network.
